.net regex match line

Why does ^.*$ does not match a line in:

This is some sample text

this is another line

this is the third line

how can I create a regular expression that will match an entire line so that when finding the next match it will return me the next line.

In other words I will like to have a regex so that the first match = This is some sample text , next match = this is another line etc...

^ and $ match on the entire input sequence. You need to use the Multiline Regex option to match individual lines within the text.

Regex rgMatchLines = new Regex ( @"^.*$", RegexOptions.Multiline);

See here for an explanation of the regex options. Here's what it says about the Multiline option:

Multiline mode. Changes the meaning of ^ and $ so they match at the beginning and end, respectively, of any line, and not just the beginning and end of the entire string.

You have to enable RegexOptions.Multiline to make ^ and $ matches the start and end of line. Otherwise, ^ and $ will match the start and end of the whole input string.
